Time Dimensions: • Long-range planning is done annually and focus on a planning horizon greater than one year; • Medium-range planning usually covers a period from 6 months to 18 months, with monthly or sometimes quarterly time increments; • Short-range planning covers a period from one day or less to six months, with weekly time increment usually.

• Process Planning determines the specific technologies and procedures required to produce a product a service. • Strategic capacity planning determines long-term capabilities (e. g. size and scope) • Aggregate planning concerns with setting up production rate by product family or other categories for intermediate term (6-18 months).
